Answer:
(D) 
Step-by-step explanation:
Given: In triangle ABC, a=9, c=5 and ∠B=120°.
To find: The value of
.
solution: It is given that In triangle ABC, a=9, c=5 and ∠B=120°.
Now, using the law of cosines, we get

Substituting the given values, we get




which is the required value of
.
Therefore, option D is correct.
Answer:
x = -1
Step-by-step explanation:
The axis of symmetry of the graph
is x=3 but,
If shift the graph 4 units to the left it would mean the new value of x would be -1 as shown here:

-4 because it shifted 4 units to the left so the axis of symmetry of the transformed graph would be x = -1 and since it shifted 2 units down the y-coordinate of the turning point would be -2 so the turning point of the original graph is (3 , 0) and the turning point of the transformed graph is
(-1 , -2) I attached an image so you can visualize clearly
